and processes of the general type described in T18. Patent No. 1,530,614, issued'March, 24, 1925 for method of metal coating, and U. S. Patent No. 1,662,537 issued March 13,

In said patents, molten metal, thrown from the molten-metal-covered articles rotated in a perforated basket, is caught by a baflie surets-received on the standards.

rounding the path of the basket; and the metal became lodged on various .parts of the machine, so that it was necessary to stop the machine to pry off the metal.

One object of the present invention is to provide a machine whereby the above mentioned inconveniences are eliminated.

'Another'object is to-provide means for preventing the cooling of theheated articles while they arebeing whirled in the basket. Other objects of the invention are to im prove generally the simplicity, economy and The inventive featuresfor the accomplishment' of these and other objects are shown herein inconnection with an improved apparatus for removing excess molten-metal from articles, said apparatus comprising means for'imparting planetary movement to a table carrying standards on the margin "of said table, between which standards is received a removable drum carrying perforated. brack- A cover on the drum is provided with a large central" opening and brackets receiving the standards and carrying releasable means engaging the is rotated.

standards to holdthe cover and drum in place. A cage is secured on'the under face of said cover undersaid large opening and is 7 adapted toreceive a perforated basket of the molten-metal-covered articles disposable entirely within said cage, to beheld therein by a removable closure held over said large opening and basket.

The movable parts of my improved apparatus for removing excess molten metal from artlcles, are carried on a pedestal 10 having a vertical bore 11 IGCQlVlIlg. fast thereln a vertical main shaftcl2 receiving loose thereon amiter pedestal.

A suitable secondary support such as a face of its side wall, perforated brackets 31 receivedon the standards for positioning the drum with the drum bottom 32 'onthe table.

A cover 34 (Fig. on said drum having alarge central opening 35, has a down-turned flange 35 receivedover the drum and carry-' ing bracket lugs carried on the outer face of said flange and having vertical bores receiving the standards. Setscrews 37 in ra-- dial threadedbores in said lugs respectively, engage said standards whereby the cover and drum may be held in place, or removed when the set screws are loosened. i

A pair of U-shaped elements 39,40 having their lower yoke parts 39 crossed and secured together, form a cage or frame'for the basket 41. The upper ends 42 of the 3 arms 40 of said elements are out-turned and received in strap sockets 43 secured to the inner margin of the under face of said cover around said large opening, whereby'the cage is rendered removably secured under the cover. The perforated basket or bucket 41 is provided with a bail 42 whereby the basket'with the Oppositely disposed perforated ears 45 are secured fast'on the top face of said'cover;

over said large opening 35- is provided with i a handle48 secured to its top face and having an extension 49 engageable in the perforation of one of'said'ears 45, while an outwardly spring pressed bolt 50 slidable in guide lugs 51', 52, and outwardly pressed by a spring 53 between the lug 52 'anda collar 54 fast on the 'bolt, is engageable in the perforation of the other ear 45, whereby the closure may secure the basket and articles in the cage.

The operation of the apparatus is very simple. moved and the parts otherwise secured as in Figs. 1 and 3, the basket 41 of hot moltenmetal-covered articles, are lowered into the cage; and the closure 47 is secured inplace. The table 28 and all parts thereon are then whirled for the desired length of time and at the desired speed, throwing'the molten After the times, it will be desirable to remove the con- .gealed metal from the drum without long delaying the use of the apparatus. This is With the closure and basket re done by loosening the set screws 37 andremoving from the table all of the parts 30 to 42 immediately replacing the parts 30 to 40 with duplicate parts held in reserve, so as not to delay the machine, and immediately proceeding with the operation as first described. The congealed molten metal can be removed from the displaced drum at any ent, and thus prevents theparticles of molten metalfrom being lodged on the machine and table '28. Heretofore it was necessary, after intervals of 20 to 50 basketfulls, to stop the machine and pry 05 the metal from the table and other parts.

The drum is quickly detachable, and instead of taking time to pry off the sheets of thrown-off metal, the operator simply lifts off the'drum', and substitutes another completedrum using the same closure as before,

hand to avoid all'interruptionof work.

Another important function of this drum is the retention of heat in and around the basket. jIn former machines the basket whirling around off center at about 360' p ,R. P. M. passes through, and creates, a conand a closure 47 (Fig. 6) disposable in and manual or other non-straight-line motion,
